SPECIFICATION forming part of Letters Patent No. 722,466, dated March 10, 1903.

7 Application filed August 20,190 2. Serial No. 120,327. (No model.)-

T0 at whom it mag concerns Be it known that 1, JOHN W. SUTTON, a citizen of the United States, residing in New York, borough of Brooklyn, and State of New York, have invented certain new and useful Improvements in Steam-Generators for Automobiles, of which the following is a specification.

This invention relates to an improved steam-generator for automobiles, in which a large number of inclined steam-coils are arranged compactly and'superposed in adjacent groups within the heating-space of the boiler, so that the quick and continuous generation of steam is'produced and simultaneously the steam which is taken from the highest point of the dome of the steam-boiler is superheated and conducted in a dry state to the motor-engine; and for this purpose the invention consists of a steam-generator for' automobiles which comprises a double-walled shell and a series of steam-coils, the ends of which are connected with the inner wall of the boiler and arranged sidewise with and superposed one above the other, each coil being ar-' ranged at a slight upward inclination from its lower to its upper terminal.

The invention consists, secondly, of a superheating spiral coil of closely-arranged convolutions supported below the dome of a horizontal steam-boiler and in the path of the products of combustion to act as a baflier to,

deflect the course of the same toward the inner wall, one end of said coil being connected with the highest point of the dome of the steam-boiler, while the opposite end of the coil is connected with the motor-engine to which the steam is conductedfor use.

The invention consists, further, of certain details of construction and combinations of parts, which will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of my improved steam-generator for automobiles. Fig. 2 is a plan view of Fig. 1. Fig. 3 is a vertical central section on line 3 3, Fig. 2. Fig. 4 is ahorizontal section on line 4 4, Fig. 1. Figs. 5 and 6 are respectively a plan view and side elevation of one of the 'interiorinclined steam-generating coils, and Figs. 7 and 8 are respectively a plan view and side elevation of one of the side inclined steam-generating coils.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the double-walled shell of my'improved steamgenerator. The double-walled shell A is rounded off at its upper end, so as to form a dome which is open at the center, the inner andouter walls of the shell being provided with overlapping flanges a a at the upper and lower ends, said flanges being connected by bolts 1) b, as shown clearly in the drawings, or they may be connected by rivets. The double-walled shell A is open at the lower end and provided with a central opening A, of smaller size in its top, so that the fire-gases can freely enter the interior of the double-walled shell and pass off at the top part of the same. At the interior of the double-walled shell are arranged tiers of inclined steam-generating coils, which are divided into two groups, one being an interior group that is disposed diametrically of the shell sidewise of each other and formed of a number of superposed coils B, one terminal of each coil passing into the interior shell,

D of steam-generating coils is arranged in the segmental space left at both sides of the interior group B, that comprises superposed coils D, which are made somewhat shorter than the coils of the interior group, as shown in-Figs. 4 and 7. The ends of the coils are bent to assume a radial position and pass through the inner wall of the shell, on which they are exterior-1y expanded. Thus the coils communicate with the annular space formed between the double walls of the shell A; Each generating-coil has an upward inclination throughout its convolutions from the lower to the upper terminal of the same, as shown clearly in Figs. 3, 6, and 8, so that the steam generated in the coils is conducted through the inner wall of the shell and to the upper part or dome of the same. The groups of interior and side coils B and D are so arranged sidcwise of each other that the heating-gases pass between the coils in upward direction, so as to play around the same and produce thereby the effective heating-up of the coils and the quick generation of steam from the water in the same. The coils are heated from the flame from any approved burner construction placed below the same and which is supplied with gasolene or other suitable hydrocarbon oil, such as is used in the motor-engines of automobiles.

At the interior of the upper part ordome of the shell A is arranged a horizontal spirally-bent coil E, the convolutions of which are closely arranged, so that the coil acts as a baffler to deflect the heated gases to spread out to the inner surface of the shell. The inner end of the horizontal coil E is connected by a pipe 6 with the higher-most point of the dome A of the steam-generator A, While the outermost end of the horizontal coil E is connected by a pipe e with the motor-engine which is to be driven by the steam. The horizontal coil E, which receives the wet steam, acts as a superheater and supplies the dry steam to the motor-engine.

Instead of the coils of the groups being superposed they may be arranged, as shown by dotted lines in Fig. 4, with alternate coils of the groups slightly staggered relatively to each other, so that the convolutions of the alternate coils are disposed partly over the spaces between the convolutions of adjacent coils. This arrangement places the coils more directly in the path of the products of combustion, causing the same to play in and out around the coils in a sinuous course, so as to distribute the heat evenly over the coils.

The water-level of the shell A is preferably at a height just below the superheating-coil E, so that the steam-generating coils can receive water at whatever inclination the generator may be placed by the ascent or descent of the motor-carriage on inclined ground. The continuous supply of Water to the steam-gencrating coils is necessary for the proper working of the generator, not only for the uniform generation of steam by the coils, but also for protecting the coils against too-rapid destruction. The superheating-coil,on the other hand,chauges the wet steam collected at the upper part or dome of the shell of the boiler and-is saturated with water particles into dry superheated steam, so that less condensation takes place in the cylinder of the motor-engine, and therefore less less by condensation during its course from the generator to the engine.

My improved steam-generator is specially adapted for automobiles, as it is of small and compact size, and is therefore specially adapted for the requirements of this class of vehicles.

Having thus described my invention, I

1. A steam-generator for automobiles, consisting of an exterior double-walled shell having a rounded-off top part or dome and tiers of superposed groups of coils, each group consisting of intermediate and side coils arranged adjacent to each other in said shell, the terminals of the coils of each group passing through the inner wall of the shell and communicating with the water-space of the generator, and the coils having a rising inclination from the lower to the upper terminals, substantially as set forth.

2. A steam-generator for automobiles, consisting of an exterior double-walled shell provided with a rounded-01f top part or dome, groups of steam-generating interior and side coils arranged adjacent to and superposed vertically above each other, the ends of said coils passing through the inner wall of the shell, and a horizontal superheating-coil of spiral form arranged above the generatingcoils, one end of said superheating-coil being connected with the highermost point of the dome of the shell, and the opposite end with the motor-engine, substantially as set forth.

3. A steam-generator for automobiles, consisting of an exterior double-walled shell provided with a rounded-01'1" top part or dome, groups of steam-generating interior and side coils arranged adjacent toand superposed vertically above each other, the ends of said coils being bent to pass radially through the inner wall of the shell and expanded exteriorly on said inner wall, and a horizontal superheating-coil arranged spirally above the generating-coils, one end of said superheating-coil being connected with the highermost point of the dome of the shell and the opposite end with the motor-engine, substantially as set forth.

4. A steam-generator for automobiles, consisting of a double-walled shell open at the lower end and rounded off into a dome shape at the upper end and provided with an opening in its upper end, groups of steam-generating coils arranged at the interior and sides of the shell, the coils of each group being arranged sidewise of the coils of the adjacent groups and vertically one above the other, their opposite ends passing through the inner wall of the shell, while the body of the coil is arranged at an upward angle of inclination from the lower to the upper terminal of the coil, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
